Noticed by Anne while walking Calcetines on Calle Bellavista this afternoon, the warm weather has triggered the processionary caterpillars to leave their nests in the pine trees.
They are clearly noticeable by the metre plus head to tail chains that they form when moving. They are a hazard to humans and in particular animals such as dogs. Their tiny barbed hairs contain a poison that can cause a severe rash and irritation to the skin, even worse if ingested.
So, please be careful and avoid if possible.
